Those look like inlet air/fuel heaters. In cold weather they will keep the fuel from puddling in the bottom of the intake port. The clean spot in the middle of them is where the injector is aimed. Cold fuel will hit the heater and vaporize. Don't know how to remove them though...

thanks a lot , they definitely look like heater
i removed them today they were held by o ring just like injector
and they are bigger than i thought ,but now i ended up with big hole in the intake , maybe i can cut them in the lower part and reinstall them
